TODO: ----- BUGS: UNSOLVED : + SuSE 9.0 : text rotation doesnt work correct (y-Axis) (see QT example "xform") + kpart in konqueror won't resize : use reload function + disable auto formatting of QT RichText (Label.cc::draw()) + opening from commandline -> maximize doesn't work correct + print preview : "qDrawShadePanel() Invalid parameters." TODO : * Debian installation problems (KDEDIR ?) * 3d : rounding of double values -> +/- 1 errors (boxes style) * 3d : plot range for box style * 3d : tic label of y and z axis are crossing * update GraphList in ListDialog, after editing data EditDialog::apply() * export data (Graph2D, Graph3D, GraphM) -> use QProgressDialog in DumpDialog * get the index of the double clicked object (for object dialog list index) * open project and clsoe LabPlot -> dont ask for saving * many times rescaling -> rounding errors in x & y direction * label position not shown when enabling axis (AxesDialog) * Data statistics with no graph -> show message * selected surface style in DataDialog is not used (standard style) * "/" for data/function separation in GraphListDialog isn't smart * "repaint" redraws always the whole Worksheet -> flicker (Qt::WResizeNoErase, Qt::WRepaintNoErase doesn't work here) * sqrt scale correct ?
